Description

本発明は、自動倉庫の棚に商品トレーを収納及びピッキングするために用いられるクレーンに関するものである。   The present invention relates to a crane used for storing and picking a commodity tray on a shelf of an automatic warehouse.

従来の自動倉庫では同一品種の物品を比較的大量にケースに収容し棚に収納していた（特許文献１、特許文献２）。
近年特に伸長が著しいネット流通では、ロングテールといわれる売れ数の少ない商品も多品種在庫をし、消費者の支持を得ている。しかしながら、膨大な商品種類の在庫管理は、従来の店舗物流の商品種類とは違い、商品を保管する棚は、広大な場所を必要とし、商品ピッキングは、棚の間を、延々と歩く作業が発生し、効率的とは言えない。従来から、ケース単位で保管できる自動倉庫もあるが、ケースを取り出し、次に補充ケースを保管するという動きであり、生産性の面から多品種・少量のバラ物流には向かない。そこでスペース生産性の高い高層棚で、多品種の商品をトレー収納し、スペース生産性とピッキング生産性を確保するためには、スタッカクレーンのケース処理の高速化など効率化が必要となる。 In conventional automatic warehouses, a relatively large amount of articles of the same type are stored in a case and stored on a shelf (Patent Documents 1 and 2).
In recent years, especially in online distribution, where growth has been remarkable, products with a small number of items sold, which are called long tails, have been stocked in various varieties and gained support from consumers. However, inventory management of a huge number of product types is different from the product types of conventional store logistics, and shelves for storing products require a vast space, and product picking involves the work of walking between shelves. It occurs and is not efficient. Conventionally, there are automatic warehouses that can be stored on a case-by-case basis, but the movement is to take out the case and then store the replenishment case, which is not suitable for high-mix / low-volume rose logistics from the standpoint of productivity. Therefore, in order to store a large variety of products on a high-rise shelf with high space productivity and secure space productivity and picking productivity, it is necessary to increase the efficiency of stacker crane case processing.
